Description

A dispensing roller structure for producing dispensing paper

technical field

The utility model relates to glue dispensing paper in the field of electrical insulating materials, in particular to a glue dispensing roller structure for producing glue dispensing paper.

Background technique

Lingge gluing insulating paper is glued on both sides. It is widely used as the interlayer insulation material of power oil-immersed transformer coils. It can also be used as the interlayer insulation material of new amorphous alloy transformer coils, or the main insulation of foil wound coils. material and end insulation. When in use, heat appropriately, and after the uniformly distributed glue is cured, the conductive coil and the insulating layer are bonded as a whole.

The manufacture of Lingge glued insulating paper is to transfer the insulating glue in the pit of the metal dispensing roller to the ordinary cable paper, and after heating and semi-curing, an insulating product is obtained. The glue point of the glue is in the form of Distributed evenly according to a certain law, the area of the roller surface occupied by glue points is about 45%, each individual glue point corresponds to the pit on the dispensing roller, the shape can be regarded as a sunken rectangle, length: 0.56mm, width: 0.56 mm, depth: between 0.2mm---0.06mm, the bottom is straight, consistent with the tangent level of the dispensing roller, produced by laser etching.

The original metal dispensing roller has the following defects. The bottom of the pit is a straight bottom, and the glue in the inner dead corner is difficult to transfer, resulting in less glue that can be transferred each time, and the glue dots are not full. If the glue is made too deep , the transfer quality is not guaranteed. At high speed, the transfer effect is even worse. After use, the glue in the internal dead corner is not easy to clean.

Utility model content

In order to solve the problems in the prior art that the glue in the dispensing pit is not easy to transfer when the dispensing roller is in use, the transfer quality is poor and the residual glue is not easy to clean. Dispensing roller structure.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a dispensing roller structure for producing dispensing paper, on which dispensing areas are evenly distributed, and the dispensing areas are diamond-shaped, each dispensing The area is composed of a number of dispensing pits. The dispensing pit is a rectangular hole dug on the surface of the dispensing roller. The bottom of the rectangular hole is a concave hemispherical bottom wall to reduce the dead corner of glue in the dispensing pit.

The four walls of the rectangular hole and the concave hemispherical bottom wall are connected by smooth arcs.

In the utility model, in order to ensure that the glue in the dispensing pit can be better transferred out, therefore, the rectangular hole on the upper part of the dispensing pit can be made into a structure with a wide top and a narrow bottom, that is, the rectangular orifice and the bottom are both rectangular. And the size of its mouth is slightly larger than that of the bottom, so that the upper walls form a structure that expands slightly upwards (its longitudinal cross-section is a trapezoid with a wide top and a narrow bottom, and the bottom of the trapezoid is a semicircular depression).

Beneficial effects: the utility model improves the structure of the dispensing pit, and sets the bottom wall of the rectangular dispensing pit into a concave hemispherical structure, so that there is basically no dead angle in it, so that the glue in it can be transferred during printing. It can be easily transferred to the dispensing paper, which avoids the trouble of the cleaning work caused by the untransferred glue remaining in the dispensing pit, and also makes the generated glue dots fuller, with stronger adhesion, and improves the dot quality. Glue speed and transfer quality.

Detailed ways

As shown in the figure, a dispensing roller structure for producing dispensing paper has a dispensing area 2 evenly distributed on the dispensing roller 1. The dispensing area 2 is diamond-shaped, and each dispensing area 2 consists of several dispensing areas. The pits 3 are arranged in an arrangement, and the dispensing pit 3 is a rectangular hole 301 dug on the surface of the dispensing roller 1 .

The above is the basic implementation of the present utility model, and can be further defined on the basis of the above:

For example, a smooth arc connection is adopted between the four walls of the rectangular hole 301 and the concave hemispherical bottom wall 302;

Or, the rectangular hole 301 on the top of the dispensing pit 3 is made into a structure with a wide top and a narrow bottom, that is, the mouth and bottom of the rectangular hole 301 are rectangular, and the size of the mouth is slightly larger than the size of the bottom, so that the four walls of the top A slightly upwardly expanding structure is formed (its longitudinal cross-section is a trapezoid with a wide top and a narrow bottom, and the bottom of the trapezoid, that is, the bottom wall of the dispensing pit 3, is a semicircular depression).

In actual production, the diameter of the dispensing roller is about 150mm, and the length is about 1300mm. The length of the upper rectangular hole 301 of the dispensing pit 3 is 0.2-0.9mm, the width is 0.2-0.9mm, and the depth is 0.06-0.3mm. The depth from the deepest part of the shaped bottom wall 302 to the bottom plane of the rectangular hole 301 is 0.01-0.1mm.
